To provide a fuel cell and its manufacturing method for restraining deformation of current collectors and a membrane-electrode assembly.
The fuel cell (100) includes a membrane-electrode assembly (10) and current collectors (20, 40) arranged on at least one surface of the membrane-electrode assembly, with gas permeability in a thickness direction and with tensile force added on an extension direction on a surface of at least a part of a region. The method for manufacturing the fuel cell (100) includes a process heating the current collectors (20, 40) having gas permeability in a thickness direction, a process fixing at least two points of the heated collectors, a process cooling the collectors fixed at least at the two points, and a process laminating the current collectors on at least a surface of the membrane-electrode assembly (10).
